Mehryar Ray Taban, Oculoplastic Surgeon, Beverly Hills. So one of the most important things you can do to achieve a more youthful face is by injecting volume, or putting more volume into the face. And there are different things, procedures are available. One is injective of fillers which they have pros and cons. They are done in the office, they're a quick in and out procedures. However, they don't last as long. The other procedure that you can do is actually putting fat into the face. You can get the fat, harvest it from the belly or the thighs, and inject it into the face. It's called fat transfer, and it gives you a youthful appearance to the face. The fat also has stem cells in there. A lot of research, research going on that has to do with the stem cells injection into the face. And those fat cells already have the stem cell. So again, they make the full, more full and rounded, as opposed to if you just do a skin pulling surgery, like a facelift they used to do many years ago. Yes, things look tighter, but they're tighter on more hollow area. Basically skin on bone. So you actually, a complimentary procedure to that would be a volume fat transfer to the face, along with the surgery.
